In LA we were fortunate to have Vin doing baseball for the Dodgers for 66 years [1950-2016], and Chick Hearn [1957-2002] for the Lakers, for over 40 years each.
And for that matter matter, Dick Enberg for 10+ years doing the Angels, Rams and UCLA Bruins [66-77 +/-] was damn good, IMO, maybe no Scully / Hearn GOAT status, but damn sweet voice for the radio, before he moved on to CBS / NBC / ESPN [1975-2011]
And ... I'm not a hockey guy, but Bob Miller had a long run of 30+ years with the Kings, and people say he was great.
And ... Ralph Lawler had a 30 year run for Clipper Nation [1987-2019]
